Remember This?

On December 4, 2017 Kardashian shared this Instagram photo of her snapping a picture at the 2016 "Famous" exhibit that featured the wax figures of her nude husban... and a naked Taylor Swift.

Caption THIS!

"Famous," Kim wrote as a caption, although most followers instantly interpreted it as a shot at Swift, labeling Kim a rat and Taylor a snake... and going back and forth on whose side they are on.

So... Many... Rats

As you can see, no one on Instagram thought this was just a harmless throwback photo. It's just unclear why Kim wanted to stick it to Taylor again.

Now We Revenge!

Down with the rat, right, folks?!?

How Did This All Begin?

In July of 2016, Kardashian released a recording of Swift giving Kanye West permission to rap about her in his track, "Famous." Swift had previously acted all pissed off about West's references to her in the song, leading many to believe Taylor was nothing but a phony and a liar.

A Swift Response

Swift said the leaked recording did NOT feature her giving Kanye permission to slam her as a "bitch," adding, famously, that she wanted to be excluded from all Kimye-related narratives.
